Question 10

The most common entry technique in sidemount diving is to put on your cylinders

• in the water.
• before a giant stride.
  -before a seated back roll

Answer 10

in the water

Question 12

Wearing all your kit including two cylinders at reserve pressure, with an empty BCD and holding a normal breath, you find you float at about eye level. This means
.
- Your weight should be about right.
- You need to remove some weight.
- You need to add some weight.

Answer 12

Weight should be about right

Question 13

During a dive in two-cylinder sidemount, you switch cylinders periodically. One reason you do this is
- to prevent the regulators from clogging.
- so your buddy knows both systems work.
- to keep both cylinders relatively close in buoyancy.

Answer 13

• to keep both cylinders relatively close in buoyancy.

Question 14

While neutrally buoyant and hovering, you find that your natural position in the water is with your feet low on a 45 angle. This means you should
Correct

• shift weight toward your feet so you are vertical.
  -shift weight toward your head so you are horizontal.
  -do nothing and maintain this trim position.

Answer 14

-shift weight toward your head so you are horizontal.

Question 15

The ____________ kick is popular because, among other reasons, it doesn’t stir up the bottom.

Answer 15

Frog

Question 16

During a dive, after using about a third of the gas in each, you notice that your aluminum cylinders seem to be rising too high at the rear. To remedy this, you may

• remove and hand carry them.
  -breathe only from one cylinder.
  -resecure them to a lower attachment point.

Answer 16

-resecure them to a lower attachment point.

Question 17

The most common exit method in sidemount is to

-remove both cylinders, then exit.
-remove one cylinder, then exit.
-remove no cylinders, then exit.

Answer 17

-remove both cylinders, then exit.

Question 18

While diving in two-cylinder sidemount, the regulator on your right cylinder suddenly fails in a runaway freeflow. After shutting the valve, your first response would be to

• breathe from your left cylinder.
  -get gas from buddy.

Answer 18

• breathe from your left cylinder

Question 19

While diving in sidemount, you’re breathing from the long-hose second stage. Your buddy signals “share air.” You will give your buddy

Answer 19

-the long-hose second stage from which you’re breathing.
